Detecting Pseudomonas aeruginosa and Staphylococcus aureus with the MolecuLight i:X™

Most potentially harmful bacteria fluoresce red when imaged with the MolecuLight i:X (e.g. Staphylococcus aureus), however Pseudomonas aeruginosa fluoresces cyan. In this patient, MolecuLight i:X images revealed both cyan and red fluorescence, which cultures confirmed to be P. aeruginosa and S. aureus. Real-time bacterial visualization and early detection of these pathogens is vital, as polymicrobial P. aeruginosa and S. aureus infections are more virulent than single pathogen infections and result in worse patient outcomes1,2. In this case, MolecuLight i:X guidance led to sampling a region with both red and cyan signals, increasing the likelihood of detecting both species.
